Estudio geotécnico in Huerta de Valdecarábanos

In Huerta de Valdecarábanos, formations of limestones, dolomites and marbles predominate, providing a geotechnical base with good bearing capacity and low deformability, generally suitable for shallow foundations. The occasional presence of gypsum, anhydrite and salts introduces the geotechnical risk of dissolution, which may affect the long-term stability of the foundations. Localised areas with compact gravels and sands offer some degree of permeability and a valid alternative for supporting structures, whereas the low presence of expansive clays minimises the risk associated with ground heave and shrinkage.

The municipality experiences moderate seismic activity, with 25 recorded events in the last 30 years, although the maximum magnitude observed (Mmax 2.2) indicates a low potential for relevant ground movements that does not constitute a primary constraint for structural design. However, the existence of karstification in the bedrock requires specific verification through in-situ studies, as it may compromise ground homogeneity and capacity; this aspect, together with the possible dissolution of gypsum and salts, is configured as the main local geotechnical constraint. The fact that the bedrock is not clayey rules out the problem of expansive soils in the area.
